6.6.5 X10 Enable-Connector

The power stage can be deactivated independent of the logic signals (X10 enable
connector).

The opto-decoupled Enable inputs A and B are used to activate the motor supply.
Both Enable inputs must be wired for activation!

The Monitor Enable output is used to check the Enable inputs A and B, i.e. when both
inputs are wired, the Monitor Enable output is set to ‚high’.
The function Enable doesn´t fulfill
‘Protection against unexpected start‘
according to EN 945-1 for application
in the extended safety sections.


The Enable inputs A and B can be permanently activated by bypassing the inputs with
the+24 V
DC
output. This will work only, if +24 V
DC
is supplied to the X4 connector.

A deactivation of the Enable signals during increasing stop and run current
values can cause an error and the axes will be stopped by an emergency stop. If
the Enable functionality should be checked e. g. after power-on, we recommend
either to reduce the current parameters or to detect the extern deactivation in the
Minilog program by commands and to reset the axes (see manual MiniLog).
Minilog command for reading the system status:
ST , Bit 5 is set (32
Dec
) = input Enable is OK
